The application of the thermocouple and advantages

Thermocouple is used more frequently in the area of modern industrial one temperature detecting element. From the point of its practical application effect, the product has many advantages. And thermocouple also includes different categories, we specially for you to introduce about the main content of the product, the hope can help you better understand the product.

first of all, we come to the simple introduced the main advantages of thermocouple. Its advantage is measuring accuracy is higher. This is because in the actual detection, we can directly contact with the object being measured, can prevent other intermediate medium influence. The second advantage is wide measuring range. Normally, the product can from - 50 ~ + 1600 ℃ condition can be edge measurement.

in some special cases, we can even use this product to - 269℃。 A third advantage is that the structure of the thermocouple is very simple, easy to use. In fact, the product is usually using a combination of two different kinds of metal wire and become, but is not limited by the size and the beginning of, outside to protect casing, which are very convenient. At the time of temperature measurement, we will mainly two kinds of different material a conductor or semi-conductor 1 and 2 welding, form a closed loop.

as a result, once appear a certain temperature difference between them, so each other can produce electromotive force. So, can form a certain size in the loop current, this kind of phenomenon called the thermoelectric effect. And our thermocouple is to work with this effect.

from the point of the current situation, we usually use the thermocouple mainly includes two kinds big, namely standard and non standard. The so-called standard is in accordance with the standard production has a certain degree of standard score table of thermocouple, this type of product can be matched display instrument selection.
